Manage Photos with gThumb
gThumb may look like yet another image viewer, but behind its unassuming appearance hides a rather capable application that can help you to manage photos efficiently.
As any decent image viewer, gThumb provides all essential tools for browsing images and performing basic operations, such as rotating and resizing graphics files, converting images to different formats, and tweaking EXIF metadata. If you use tags to keep tabs on your photos, you’ll appreciate gThumb’s tag editing feature. To quickly assign one of the existing tags to a specific photo, right-click on it and choose the desired tag from the Tags menu. Choose the Other item to add new tags and assign them to the photo. To specify additional metadata, press the Comment button on the main toolbar, and fill out the available fields.
